2nd Yellowstone grizzly could be killed in mauling of Michigan man

Yellowstone National ParkA grizzly bear moves through the brush in June 2005 in Yellowstone National Park in Wyoming.

A second grizzly bear could be killed in connection with the fatal mauling of a Michigan man at Yellowstone National Park last summer.

Park superintendent Dan Wenk discussed the possibility on KODI-AM earlier this month. Park spokesman Al Nash said Tuesday that no date has been set for a decision.

One grizzly was euthanized last fall after it was linked to the scene of 59-year-old hiker John Wallace's death. DNA tests show the bear killed a California hiker and also fed on Wallace but officials aren't sure if the sow killed Wallace.

Hair from the second bear at issue was found about 22 yards away from where Wallace died but test results didn't come back until after bears entered hibernation. That bear, which has a radio collar, is still in its den.
